Design patterns represent common software problems and the solutions to those problems in a formal manner. They were inspired by a book written by architect Christopher Alexander. Patterns were introduced in the software world by another book: "Design Patterns: Elements of Reusable Object-Oriented Software", by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides. These people were nicknamed the "Gang of Four" for some mysterious reason. The Gang of Four describes 23 design patterns. With patterns you don't have to reinvent the wheel and get proven solutions for frequently encountered problems. Many books and articles have been written on this subject. This means that design patterns are becoming common knowledge, which leads to better communication. To summarize design patterns save time, energy while making your life easier.

In this code snippet we are going to provide you with a way to expose your existing ASP.Net application so it can be exposed as a Web service. If you're not familiar with Web services, they provide you with a means to expose the functionality of your application to other clients over the Web. For example, here at WWWCoder.com we provide our directory as a Web service to clients so they can integrate the directory into their portal site. Here is an online example of what I'm referring to. You can see from that site, they are using our directory integrated into the look and feel in there site. All data is being feed by our Web service hosted here at WWWCoder.com. We provide a module snap-in for their DotNetNuke portal so they can integrate the directory into their site.
